Samuel PepysPRS, MP, JP, (; 23 February 1633 – 26 May 1703) was an English naval administrator and Member of Parliament who is now most famous for the diary he kept for a decade while still a relatively young man. Although Pepys had no maritime experience, he rose by patronage, hard work, and his talent for administration to be the Chief Secretary to the Admiralty under both King Charles II and subsequently King James II.
